Regarding 1.:
Not sure why, but nice guy here has done some more (research) work for Sven:

Quote from official YT support:
The Warp 6 template Balance offers a "mobile" layout which is triggered by the [b]browser agent[/b] alone.
But technically it is [b]not responsive[/b], meaning it does [b]not[/b] use CSS @media queries to change the layout based on the resolution.
Further links below that post.
Since all WARP 6 templates use that same framework, indeed, this is then true for Big Easy, too.
Even if risking to hit an overly sensitive nerve again (

), I can't emphasise enough how wonderfully helpful product documentations and forum "Search" functions can be, especially if accessible for those who need to know. Not to mention a minimum sense of humour.
Sven, this is guaranteed my last post in this thread, case closed for me, and accordingly, here already my thanks in advance for your thanks.
